Benjamin finds some nickels and quarters under the couch cushions. How many
coins does he have if he has 8 nickels and 12 quarters? How many coins does he have
if he has a nickels and y quarters?
Benjamin has 340 cents or $3.40.
What is Proportion?Proportion in Mathematics is an equation where two or more ratios are made to be equal.
If a : b = c : d, then we can write a/b = c/d
We know that,
1 nickel = 5 cents
8 nickel = x cents
Using ratio and proportion,
1 : 5 = 8 : x
x = 8 × 5 = 40 cents
Similarly,
1 quarter = 25 cents
12 quarters = 12 × 25 = 300 cents
Total cents Benjamin has = 300 + 40 = 340 cents = $3.40
Hence, Benjamin has a total of $3.40.

a Iris is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 25 represents the number of flowers that bloomed, where s is
seeds she planted. The function s(w) = 25w represents the number of seeds she plants per week, where w represents the number of weeks.
Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks. (4 points)
Part B: What are the units of measurement for the composite function in Part A? (2 points) (2
Part C: Evaluate the composite function in Part A for 30 weeks. (4 points)
A) Composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks is f[s(w)] = 50w + 25.
B) The unit of measurement for the composite function is flowers.
C) Number of the flowers for 30 weeks will be 1525.
What is a composite function?A function is said to be a composite function when a function is written in another function. The composite function that represents the number of flowers is f[s(w)] = 50w + 25. and the number of flowers for 30 weeks is 1525.
Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks.
From the given data we will find the function for the number of flowers with time.
f(s) = 2s + 25
We have s(w) = 25w
f[(s(w)]=2s(w) + 25
f[(s(w)] = 2 x ( 25w ) +25
f[s(w)] = 50w + 25.
Part B: What are the units of measurement for the composite function in Part A
The expression f[s(w)] = 50w + 25 will give the number of the flowers blooming over a number of the weeks so the unit of measurement will be flowers.
Part C: Evaluate the composite function in Part A for 30 weeks.
The expression f[s(w)] = 50w + 25 will be used to find the number of flowers blooming in 30 weeks put the value w = 30 to get the number of the flowers.
f[s(w)] = 50w + 25.
f[s(w)] = (50 x 30) + 25.
f[s(w)] = 1525 flowers.
Therefore the composite function is f[s(w)] = 50w + 25. unit will be flowers and the number of flowers in 30 weeks will be 1525.

Triangular altitude theoremA triangle is a shape with 3 sides and angles.
According to the theorem
CD/BD = BD/DA
From the given figure
CD = DA = 14/2
CD = DA = 7
Substitute
7/BD = BD/7
BD² = 7²
BD² = 49
BD = 7
Determine the measure of BC

The functions f(x) and g(x) are shown on the graph.
The image shows two graphs. The first is f of x equals log base 3 of x and it is increasing from negative infinity in quadrant four as it goes along the y-axis and passes through 0 comma 1 to turn and increase to the right to positive infinity. The second is g of x and it is increasing from negative infinity in quadrant two as it goes along x equals negative 4 and passes through 0 comma negative 3 to turn and increase to the right to positive infinity.
Using f(x), what is the equation that represents g(x)?
g(x) = log3(x) – 4
g(x) = log3(x) + 4
g(x) = log3(x – 4)
g(x) = log3(x + 4)
Answer:
[tex]g(x)=\log_3(x+4)[/tex]

Translations
For [tex]a > 0[/tex]
[tex]f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]
[tex]f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}[/tex]
[tex]f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}[/tex]
Parent function:
[tex]f(x)=\log_3x[/tex]
From inspection of the graph:
The x-intercept of [tex]f(x)[/tex] is (1, 0)The x-intercept of [tex]g(x)[/tex] is (-3, 0)If there was a vertical translation, the end behaviors of both g(x) and f(x) would be the same in that the both functions would be increasing from -∞ in quadrant IV.
As the x-intercepts of both functions is different, and g(x) increases from -∞ in quadrant III, this indicates that there has been a horizontal translation of 4 units to the left.
Therefore:
[tex]g(x)=f(x+4)=\log_3(x+4)[/tex]
Further Proof
Logs of zero or negative numbers are undefined.
From inspection of the graph, [tex]x=-3[/tex] is part of the domain of g(x).
Therefore, input this value of x into the answer options:
[tex]g(-3)=\log_3(-3)-4\implies[/tex] undefined
[tex]g(-3)=\log_3(-3)+4\implies[/tex] undefined
[tex]g(-3)=\log_3(-3-4)=\log_3(-7)=\implies[/tex] undefined
[tex]g(-3)=\log_3(-3+4)=\log_3(1)=0[/tex]
Hence proving that [tex]g(x)=\log_3(x+4)[/tex]
The equation that represents g(x) is: [tex]g(x) = log_3(x + 4)[/tex]
The correct answer is: the fourth option:
[tex]g(x) = log_3(x + 4)[/tex].
Here, we have to find the equation that represents g(x) using f(x), we need to consider how the graph of g(x) is related to the graph of f(x).
The graph of f(x) = log base 3 of x starts from negative infinity in quadrant four, passes through (0, 1), and increases to positive infinity.
The graph of g(x) is increasing from negative infinity in quadrant two, passes through (0, -3), and increases to positive infinity.
So, we can see that the graph of g(x) is the graph of f(x) shifted 4 units to the left along the x-axis.
Therefore, the equation that represents g(x) is:
[tex]g(x) = log_3(x + 4)[/tex]
The correct answer is: the fourth option:
[tex]g(x) = log_3(x + 4)[/tex].

The function f(x) = 2x2 + 3x + 5, when evaluated, gives a value of 19. What is the function’s input value?
Answer:
-7/2 or 2 are inputs that give 19 as output.
Step-by-step explanation:
The problem gives us a quadratic function [tex]\displaystyle \large{f(x)=2x^2+3x+5}[/tex]. When its output is 19, we want to know the input value(s).
Since an output which is f(x) = 19. Therefore:
[tex]\displaystyle \large{19=2x^2+3x+5}[/tex]
Rearrange the expression in quadratic equation.
[tex]\displaystyle \large{0=2x^2+3x+5-19}\\\\\displaystyle \large{0=2x^2+3x-14}\\\\\displaystyle \large{2x^2+3x-14=0}[/tex]
Factor the expression.
[tex]\displaystyle \large{(2x+7)(x-2)=0}[/tex]
Solve like linear equation which we get:
[tex]\displaystyle \large{x=-\dfrac{7}{2}, 2}[/tex]
If you input these x-values in the function, you will get 19 as the output which satisfies the condition.
Hence, inputs are -7/2, 2
Answer:
[tex]x=2, \quad x=-\dfrac{7}{2}[/tex]
Step-by-step explanation:
Set the function to 19:
[tex]\implies 2x^2+3x+5=19[/tex]
Subtract 19 from both sides:
[tex]\implies 2x^2+3x-14=0[/tex]

Find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]: 7 and -4

Factorize the first two terms and the last two terms separately:
[tex]\implies 2x(x-2)+7(x-2)=0[/tex]
Factor out the common term (x - 2):
[tex]\implies (2x+7)(x-2)=0[/tex]
Therefore the function's input values that when evaluated give a value of 19 are:
[tex](2x+7)=0 \implies x=-\dfrac{7}{2}[/tex]

Complete questionAt a certain college, 49% of the students are female, and 21% of the students major in civil engineering. Furthermore, 8% of the students both are female and major in civil engineering. What is the probability that a randomly selected female student majors in civil engineering?
How to determine the probability?Let A represent Female and B represents civil engineering.
The above representation means that the given parameters are:
P(A) = 49%P(B) = 21%P(A and B) = 8%The required probability is calculated as:
P(A or B) = P(A) + P(B) - P(A and B)
This gives
P(A or B) = 49% + 21% - 8%
